Got an Mac? I need your help. I want to find out a bit more about the hardware that’s in various Intel Macs – specifically about built-in PCI devices with onboard expansion ROMs. You can help me out by sending me the output of lspci -vv on your Mac. The only catch is you need to install a kernel extension to do it. But don’t worry, it’s software written by the CoreBoot dudes! They’re trustworthy, I swear!

EDIT2: I’ve had a couple of people having trouble building DirectHW. I’ve uploaded binaries here and here if you don’t want to build/have trouble building from source (and trust me).

The mission is dangerous, but if you’re ready, willing and able, this is what you need to do:

You’ll now have those two disk images created at the paths displayed at the end of the make processes. Install the packages in each of the DMGs, and then load the kernel extension:

$ sudo kextload /System/Library/Extensions/DirectHW.kext

EDIT: Oh I forgot, please turn off the energy saver setting (on laptops) to automatically switch graphics or whatever, so the non-integrated graphics card is powered on. You might need to log out and back in before it is powered on.
